Optimising glyphosate efficacy to control alien invasives
Hestia Nienaber-ARC- Small Grain Institute
Glyphosate is a broad spectrum, non- selective systemic herbicide. It is effective in killing all plant types including grasses, perennials, woody plants and alien invasive species.
Glyphosate is one of only few herbicides registered for use on alien invasive species.
However, when glyphosate mixed with carrier waters that contain high salt levels, the activity of glyphosate is reduced as a result of chemical modification of the herbicide. This effect is known as antagonism in the spray mixture.
